How to fix the firebase error I get after importing firebase auth in my dart file in flutter app?

Question

I have been facing this error for weeks now, I simply can't use firebase anymore in my app. I created a new application then added firebase as required. Immediately I import firebase auth in my application I get a bunch of error. I've tired created several app and added firebase to it but still got this error. Followed tutorial to no avail

Here is my pubspec.yaml file

dependencies:
  flutter:
    sdk: flutter
  firebase_core: "^0.5.3"
  firebase_auth: "^0.18.4"
  cloud_firestore: "^0.14.4"

my dart file

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_auth/firebase_auth.dart';

class AuthService {
  static final _auth = FirebaseAuth.instance;
  static final _fireStore = FirebaseFirestore.instance;

  static Future<bool> signUp(String name, String email, String password) async {
    try {
      UserCredential authResult = await _auth.createUserWithEmailAndPassword(
          email: email, password: password);

      User signedInUser = authResult.user;

      if (signedInUser != null) {
        _fireStore.collection('users').doc(signedInUser.uid).set({
          'name': name,
          'email': email,
          'profilePicture': '',
          'coverImage': '',
          'bio': ''
        });
        return true;
      }

      return false;
    } catch (e) {
      print(e);
      return false;
    }
  }

}
